I have an e switch that does not recognize my joycon I have tested the rail twice with several joycons always loaded to the maximum. Change the PU Chip.
In hard reset mode the right joycon does not appear. when I start the switch (see video) the joycon clicks but still does not work.
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
